Hi,
I did my ppl there a while back and the place was fantastic. I stayed in the Wellesley, which was very well priced and the accomodation was great. Breakfast was a bit boring though. I did my ppl from zero hours in 21 days.
Just a tip that I found great, instead of hiring their crappy bikes, pop to walmart and buy a bike! You can get one for around $80 and then sell it to someone when you leave. I did that and then sole it for $60 when I left. Its much cheaper and you get a brand new bike! If there is no one to sell it to, the school may buy it from you too.
Have fun in Naples!
